Question

The handpiece that uses mechanical, radiant water energy and sound vibrations to create a pulsating effect on a tooth surface for the removal of calculus and stains is the ____________ handpiece?

1) Ultrasonic
2) Air-driven
3) Electric
4) High-speed

Answer 1

The handpiece that utilizes mechanical, radiant water energy, and sound vibrations for dental cleaning is the Ultrasonic handpiece. It works through ultrasonic waves causing cavitation which cleans effectively by reaching into crevices on the tooth surface.

Step-by-step explanation:

The handpiece that employs mechanical, radiant water energy, and sound vibrations to create a pulsating effect for the removal of calculus and stains is known as the Ultrasonic handpiece. This type of handpiece uses ultrasonic waves, typically around 20 to 40 kHz, to create agitation in the cleaning fluid. The energy from the vibrating tip causes the formation and collapse of millions of microscopic bubbles in the liquid, a process known as cavitation.

Cavitation can generate powerful shock waves within the fluid that are capable of reaching into small crevices, effectively removing debris and stains from the tooth surface. Ultrasonic cleaning is an efficient method for oral hygiene as it can pulverize tissue, remove plaque, and prevent the accumulation of tartar, thus aiding in minimizing cavities and periodontal disease.
